Definitions

  • the disclosure relates to a cellular handset device with a configurable hardware circuit for processing a radio signal according to a first hardware capability set, in particular for a global navigation satellite system (GNSS) service, in a first operation mode and for processing a radio signal according to a second hardware capability set, in particular for a metropolitan beacon system (MBS) service, in a second operation mode.
  • GNSS global navigation satellite system
  • MBS metropolitan beacon system
  • the disclosure particularly relates to techniques for reusing modem capabilities for MBS services.
  • Terrestrial beacon systems 120 offer a far better performance for indoor positioning, but induce a cost adder.
  • cellular functionality needs to be given up.
  • costly additional front-end structures 121, 122 for using terrestrial beacon systems 120 must be provided as shown in Fig. 1 .
  • Existing network protocols assume that the user equipment (UE) has a certain set of capabilities, and needs to follow network configuration command. Once UE communicated its capabilities and the network configuration command has been communicated to the UE 101, the UE must comply for the duration of the current network registration. As consequences, there is no flexibility in the system to reapply for new set of capabilities assuming those capabilities are dynamically changed. It is most desirable for rare cases such as e911 call to use terrestrial beaconing system.
  • Document US 2010/277252 A1 discloses a multi-mode radio frequency front end module.
  • Document EP 2 375 803 A1 discloses a multi-mode radio access network controller entity with dynamic re-configuration for supporting at least two different radio access technologies.
  • Document US 2015/0133171 A1 discloses a method and system for implementing a dual-mode dual-band GNSS/M-LMS pseudolites receiver.
  • GNSS global navigation satellite system
  • MBS Metropolitan Beacon System
  • a GNSS capability set is a set of hardware functions that supports the global navigation satellite system, i.e. a satellite navigation system with global coverage.
  • a satellite navigation system is a system that uses satellites to provide autonomous geo-spatial positioning. It allows small electronic receivers to determine their location to high precision (within a few meters) using time signals transmitted along a line of sight by radio from satellites.
  • An MBS capability set is a set of hardware functions that supports navigation by the MBS system.
  • Metropolitan Beacon System (MBS) is a precise three dimensional location and timing technology designed to provide services to entire metropolitan areas where GNSS or other satellite location signals are blocked or can't be reliably received.
  • the devices and methods described in the following may use hardware that supports the NextNav network.
  • the NextNav network uses Metropolitan Beacon System technology to deliver high precision three-dimensional indoor location capabilities across a market area.
  • MBS is built on principles similar to GPS transmitting precisely timed signals from a network of wide-area beacons enabling receivers to use trilateration techniques to determine their precise location. This differs significantly from other approaches to indoor and urban location relying on short-range, local-area transmitters.
  • MBS is built on principles similar to GPS, transmitting precisely timed signals from a network of wide-area beacons enabling receivers to use trilateration techniques to determine their precise location.
  • NextNav operates its MBS network over its spectrum licenses in the 920-928 MHz band.
  • E911 is a system used in North America that links emergency callers with the appropriate public resources. In North America, the system tries to automatically associate a location with the origin of the call. This location may be a physical address or other geographic reference information such as X/Y map coordinates. The caller's telephone number is used in numerous manners to track a location that can be used to dispatch police, fire, emergency medical and other response resources.
  • E911 exists not only in the US, there are a variety of E911 systems in Europe as well and it is a part of the 3GPP standard in some of its variation. There are multiple E911 methodologies, the special requirements in the US is that the FCC is mandating E911 with location indoor (MBS or similar) and outdoors as well.
  • a corresponding device configured to perform the method and vice versa.
  • a corresponding device may include a unit to perform the described method step, even if such a unit is not explicitly described or illustrated in the figures.
  • the features of the various exemplary aspects described herein may be combined with each other, unless specifically noted otherwise.
  • the techniques described herein may be implemented in wireless communication networks, in particular communication networks based on high speed communication standards from the 802.11 family according to the WiFi alliance, e.g. 802.11ad and successor standards.
  • the methods are also applicable for mobile communication standards such as LTE, in particular LTE-A and/or OFDM and successor standards such as 5G.
  • the methods and devices described below may be implemented in electronic devices such as cellular handsets, mobile or wireless devices (or mobile stations or User Equipments (UE)).
  • the described devices may include integrated circuits and/or passives and may be manufactured according to various technologies.
  • the circuits may be designed as logic integrated circuits, analog integrated circuits, mixed signal integrated circuits, optical circuits, memory circuits and/or integrated passives.
  • Fig. 2 is a schematic diagram illustrating a communication system 200 with a cellular handset device 201 according to the disclosure.
  • the cellular handset device 201 includes a configurable hardware circuit 202 and a hardware manager 320 (described in detail below with respect to Fig. 3 ).
  • the hardware circuit 202 is configured to process a radio signal 210, 220 according to a first hardware capability set 211 when configured for a first operation mode and according to a second hardware capability set 212 when configured for a second operation mode.
  • the radio signal may be a satellite signal 210 received from a satellite of a GNSS system 110 or alternatively a terrestrial radio signal 220 received from a terrestrial beacon system 120 such as an MBS system.
  • the hardware manager is configured to change an operation mode of the hardware circuit 202 between the first operation mode and the second operation mode responsive to a hardware capability change request. This hardware capability change request may be initiated from a cellular network or initiated by a higher application layer of the cellular handset device 201.
  • Figure 2 illustrates a communication system 200 for changing cellular handset (UE) capability on-the-fly in order to enable terrestrial beacon system features.
  • UE cellular handset
  • the GNSS system 110 and the MBS system 120 are only exemplary services to illustrate the reconfiguration of the hardware circuit 202. Any other service where different hardware capability sets are required can be implemented by such a mobile device 201 as well.
  • the basic principle is to reuse existing receiver resources that share similar characteristics, e.g. terrestrial beaconing system 120 for indoor positioning (such as NextNAV) operating at 915 MHz bandwidth LTE band 8 operating at 920-925MHz.
  • the UE will re-configure itself and may be required to notify the network.
  • the device needs to apply for reconfiguration via capabilities change request from the cellular network.
  • the cellular network will accept or reject it according to its network policy.
  • the UE capability request may be initiated by the network (e.g. after e911 services activated). The network in most cases will acknowledge to such request assuming it is designed for it.
  • the UE will reuse the existing infrastructure after confirmation from network arrives as long as it requires by the capability (e.g. till the e911 service being served) and reconfigure back to its default capabilities. This may also require to be notified that the device capabilities were restored.
  • the cellular handset device 201 described herein supports UE capability reconfiguration, i.e. an RX chain (e.g. as described below with respect to Fig. 3 ) can be reused without duplicating or extending it with another external integrated circuit (IC) 122 as shown in Figure 1 .
  • This functionality is mostly appealing in devices that are designed to be used world-wide where a subset of the feature set or partial regulatory requirements apply only to specific regions (e.g. e911 services which are mandatory only in North America).
  • the UE will be able to "hijack" certain circuit to be served temporarily and to restore to its original purposes after the service has been served.
